..., and interlayered pyritic argillite and mudstone of the Mystic Creek Member of the Totatlanika Schist Formation. Mystic Creek metarhyolite and alkali basalt (Chute Creek Member) constitute a bimodal pair that formed in an extensional environment. A synvolcanic peralkaline quartz porphyry containing veins...

... rocks of the Mystic Creek Member of the Totatlanika Schist. Water samples with the lowest pH (many below 3.5), highest specific conductance (commonly >2500 μS/cm) and highest major- and trace-element concentrations are from springs and streams within the quartz–sericite–pyrite alteration zone...

... northeast of the Salcha River gneiss dome, in a topographically high area that includes rugged West Point peak (Fig. 4) . Prior to our U-Pb dating of these rocks, the only age control consisted of conodonts of Middle Devonian to Early Mississippian age at one location within the Mystic Creek Member...

... in these localities are thought to roughly overlap in age with Mississippian–Permian units in the Mystic Pass and Farewell Lake–Sheep Creek localities, exposures are sparse and very limited. This study focuses on Mississippian–Permian stratigraphy exposed in the northwestern Talkeetna quadrangle (Mystic Pass region...

... that of the fossiliferous sandstone. It has some statistical similarity to samples 11AD2A (Sheep Creek Formation; Fig. 7A ) and 03ADw415C (lower Mystic assemblage; Fig. 8A ), producing PDP cross-correlation coefficients of 0.51 and 0.58, respectively (Table S3 [ footnote 1 ]; Saylor and Sundell, 2016 ). Otherwise...

... for the three limestone members of the Fort Scott formation and he (letter dated, January 5, 1940) has kindly consented. Greene proposes to substitute the name Blackjack Creek limestone for lower Fort Scott. For a type locality he refers to outcrops in Johnson County mentioned by Hinds (1912, p. 220); “Four...

... (augen orthogneiss in the California Creek Member of the Totatlanika Schist) and 367 ± 4 Ma to 356 ± 3 Ma (metarhyolite in the Moose Creek and Mystic Creek Members of the Totatlanika Schist) ( Dusel-Bacon et al., 2004 , 2012 ). Most of the metarhyolite in the Mystic Creek Member is interpreted...

... and argillaceous dolomites which range in thickness from 20 to 45 ft, is conformable on the Connell Sandstone Member but unconformable beneath the massive carbonate rocks of the Montoya Group. In subsurface, the carbonate rocks of the Oil Creek Formation underlie the Waddell Sandstone Member of the McLish...

... the likelihood of a rupture jumping across the stepover. Our new cone penetration test ( CPT ) and trench observations along the Claremont fault at Mystic Lake indicate that the main strand of the Claremont fault has jumped nearly a half kilometer westward into the San Jacinto releasing stepover during the late...

... bottom to top are the Bull Creek Member, Bee Cave Member, Cedar Park Member, Whitestone Member, Keys Valley Member, and an unnamed “upper marl member.” The Bull Creek Member is made up of hard, burrowed, nodular limestone. In the western Austin area of Travis County, the Bull Creek Member varies...

... the limestone closely overlies the very pimply, black, sheety roof shale of the coal which also in both states locally rises considerably above the coal, because of the presence of the lenticular Francis Creek shale. Other members of the Oak Grove succession have not been certainly recognized in Iowa...

... lithologic and faunal features that suggest ties to the Farewell terrane ( Blodgett et al., 2002 ; Dumoulin et al., 2014a ). Lower Paleozoic rocks in the White Mountains terrane comprise a mafic volcanic succession (Ordovician Fossil Creek Volcanics) overlain by shallow-water carbonate strata (Silurian...

... of the Cow Head Group and Lower Head Formation. James and Stevens (1986) mapped the whole group in great detail and formally established two formations and seven members ( Fig. 3 ). The two formations reflect both the nature and depositional setting of the Cow Head Group sediments. The Shallow Bay...
